Problems solved by technology

However, the flux used in the prior art usually contains glutaric acid, which causes the flux to absorb moisture easily, so that the produced power charger single panel is easy to absorb moisture and cause product quality problems when it rains and is wet in spring. question
In addition, the resistance value of the soldering flux commonly used in the prior art is not high enough, so that the insulation of the single-sided circuit after soldering is not ideal.

Abstract

The invention relates to the technical field of soldering flux, in particular to high-impedance soldering flux for a single panel of a power source charger and a preparation method of the high-impedance soldering flux. The high-impedance soldering flux for the single panel of the power source charger consists of the following ingredients in percentage by weight: 1 percent to 5 percent of hydrogenated rosin, 0.1 percent to 0.8 percent of adipic acid, 0.4 percent to 1.2 percent of sebacic acid, 1 percent to 3 percent of succinic acid, 0.5 percent to 2 percent of glycollic acid, 0.1 percent to 0.8 percent of dibromo butylene glycol, 0.5 percent to 2 percent of surface active agents, 2 percent to 7 percent of film forming additives and 80 percent to 92 percent of absolute ethyl alcohol. The high-impedance soldering flux for the single panel of the power source charger has the advantages that the moisture cannot be easily absorbed, so the single panel of the power supply charger is prevented from generating quality problems caused by moisture absorption in rainy humid weather in spring, and in addition, the single panel of the power supply charger has the characteristic of high impedance.

Description

technical field [0001] The invention relates to the technical field of soldering flux, in particular to a high-impedance soldering flux for a single panel of a power charger and a preparation method thereof. Background technique [0002] When producing the single panel of the power charger, it is necessary to use flux to weld the circuit of the single panel. However, the flux used in the prior art usually contains glutaric acid, which causes the flux to absorb moisture easily, so that the produced power charger single panel is easy to absorb moisture and cause product quality problems when it rains and is wet in spring. question. In addition, the resistance value of the flux commonly used in the prior art is not high enough, so that the insulation of the surface of the single-sided circuit after soldering is not ideal. Contents of the invention [0003] The object of the present invention is to aim at the deficiencies in the prior art, provide a kind of high-impedance so...
